Abstract

An image forming method comprising imagewise exposure and color development of a multilayer silver halide color photographic material comprising a support having thereon at least one silver halide light-sensitive emulsion layer containing at least one oil-soluble coupler which is capable of forming a substantially non-diffusible cyan dye upon coupling with an oxidation product of an aromatic primary amine developing agent and which is represented by formula (I), and at least one compound selected from the group consisting of compounds represented by formula (II) or (III) followed by the processing of the multilayer silver halide color photographic material with at least one of a bleaching solution and bleach-fixing solution each having a pH of not higher than 6.3, wherein formula (I), (II) and (III) comprise ##STR1## wherein Y represents --NHCO-- or --CONH--; R.sub.1 represents an alkyl group, an aryl group, a heterocyclic group or an amino group; X represents a hydrogen atom, a halogen atom, an alkoxy group or an acylamino group; R.sub.2 represents an alkyl group or an acylamino group, or X and R.sub.2 together represent a non-metallic atomic group necessary for forming a 5-membered, 6-membered or 7-membered ring; Z represents a hydrogen atom or a group capable of being released at the time of coupling with the oxidation product of the developing agent; R.sub.3 and R.sub.5 each represents a halogen atom, an acyl group, an alkyl- or arylsulfonyl group or a carbamoyl group, R.sub.4 and R.sub.6 each represents a hydrogen atom, an alkyl gorup, an aryl group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group or an amido group; and the total number of carbon atoms included in the groups represented by R.sub.3 and R.sub.4 or the groups represented by R.sub.5 and R.sub.6 is not less than 8.
